Cakeonit, Love your narrative. Know exactly what you went through.
Was the power supply the only change to get it staying on? I'm having the same problem with a 700 and just like with you crickets for answers. I'll try it.
Kuschelweich, do you only fix the cooling system? Feel free to pm me
I've never actually had one and don't really know much about the cooling system. Just figured it might be fun to try and fix one if it's cheap enough. I was going to purchase some "working" ones when the profitability was better, but seeing how many have cooling system issues I'm thinking it might not be worth the risk.
